Toca` whom 'it may concem.

Be it known that I, BRUNO R. G. `DARR,-. a subject of the Emperor of Germany, and resident of the city of kNew York, in the vcounty of New York and State of New York,I havel invented certain new and usefull Improvements in Automobile-Tires, of which the following is a specification.

This invention relates to improvements in .automobile tires.

In the drawings Figure 1 is a cross sec- .tion of a tire constructed and arranged in accordance with this invention. Fig. 2 is a cross-section of the parts shown in'Fig. 1, -said partsbeing deflated, andthe flaps left anging`.-` -Figf. 3 is a" side view of one-half of -thewheehthe view being taken on the side ofthewh'eelI to showthe securing hooks for ithe outer flap. Eig. 4 is a similar View taken from the? opposite side of the wheel.

.The principal object which this invention has in; `View is to: provide suitable .thick -wall protection pieces for the inner tube of a his directly,

pneumatic tire. Also toprovide a structure of the characterspecified which. facilitates the removal and'replacement of the protectin` flap whichhas been subjected to wear.

vith-v theseobjects in view- I have* provided a metal rim. or felly, 2, having a channel;,"3, provided onthe outer side 'of the Wheel.l This channel is extended V,outward to perr'nit a line. of rivets to be driven above jthecliannel `for-securing rigidly to this part of thestructurgthe inner protecting flap as after more fully set forth. The opite ofthe rim2, is provided with lie extensions, 4, and 5,. the latter being set outk laterally to receive the fastenings for lthe outer'protectinglap. Within the pro- -testing 'lla-ps, 6, and-"2:7, is carried the exjpansible rubber inner' tube, 8. This exansibletube, 8, is of the usual construction.

covered by the inner protecty 'lap, 6. This may be constructedof specially prepared canvas, or of leather. It maybe further provided on the tread with the usual puncture proof armor construction. Itis secured to the one edge to the 'rim-just above the channel, 3. This securement is by means of rivets, 9. The flap is made in a semi-tubular shape. When the filmer tube is deflated this permits the free edge of the flap, 6, to pass across the rlm, 2, over the inner tube, 8. The free' edge 1s somewhat lengthened to allow it to extend well up into `the rim, and into the valley A thereof, betweenthe metal and the inner` tube,.8.

The outer protectingllap, 7,-is rigidly secured tothe rim, 2, and to the extension, 5, thereof, by means of the flap, 7, is preliminarily secured within a U-shaped holding ring, 11. The ring is pertween the walls thereof. The vflap, 7, is provided with thetread, 12, andis generally constructed as heavy as possible. At the free edge it is cut into sections, 13,- that are provided with securing plates, 14, the plates being secured -by means of rivets, 15. These plates are provided at the-upper edge with hooks,1 16, constructed to pass over the edge of the upturned metal which forms the channel, 3, lof `the rim. NVhen in position these metal sections.l are formed to abutv each upon the other ings. 13, are separated as closeto the tread, 12, as is .found-necessary in order that the tube may bebrought sidewise over the inner flap, 6, and inner tube', 8, when the same is deflated.

hen constructed as specified -and as The sections,

-shown in the accompanying drawings the operation is as follows :-Bcfore placing the inner tube, 8, in position the flap, 6, is riveted upon therim as shown and described. The inner tube, 8, is vs ecured in'position on the rim by the usual method, and while in its de-j fiated condition the flap, G, is brought over and extended up between the extension, el, of the rim and the inner tube as shown. The outer protecting tlap, 7, is provided with the ring,11,`which as stated is perforated to re-.

ceive the small bolts, 10. They are bolted into position thereby `rigidly,"securing the edge of the tlap, 7, to the rim of the wheel. The flap, 6, being in position the flap, 7, is carried over the flap, 6, tothe other side of the wheel rim andV platos, 14, carrying the hooks, 16, are placed 1n position withinthe channel, The inner tube is no W inflated; in which operation the loose parts to wit, the two i'laps are moved outward and until the lfurther movement is arrested of the tiap, 7 the rotundity of the completed tire is now complete. f

A, particular advantage gained'by this construction is, that in event of accident to either the flap, 7. or the inner tube, 8. a repaircan be easily and quickly. made,- necessitating only tbat the tube, 8,.sl'1ould be deflated and collapsed allowing tlichooks, 1G, to be' wltlias shown in Fig.- 3 of drawbolts, 10Q This edge of forated when the-edge of the flap, 7, 1s befdrawn from their engagement with the channel, 3, and the flap, 7 to be drawn back from over the parts,t1ap, 6, and tube, 8. It the in- ;juiy be to the inner tube, the flap, 6, is now dravvn back, and the inner tube. 8 is eX- posed, or may be quickly removed. if as is usual, the injury be to the outer ap, 7, it is evident that this may be readily repaired. Should the injury be of so serious a character as to Warrant the removalof the iiap, 7, this is i'eadily e'lected by removing the iiap, 7, releasing it from the bolts, 10, which are not many in number, and thereby removing the ring, ll, with the flap, A further advantage in this construction isthat. touring cars, and others provided for an emergency accident, may carry a flap, 7, which makes a small parcel instead of, as now, a heavy shoe or complete tire.

i-laving thus described this invention it is claimed.
